To all whom it may concern.-

Be it known that I, HIRAM H. HERRICK, of Boston, in the State of ll/lassachusetts, have invented certain new and useful Improvements in Nutmeg-Graters and I hereby declare that the following is a true and exact description of the same, reference being had to the accompanying drawings, and to the letters of re'erence marked thereon.

The nature ot' my invention consists in the use of certain mechanical devices to facilitate the grating of nutmegs.

Figure l in the annexed drawingsrepre'sents a vertical section of my machine. Fig. 2 is a side elevation of the same.

The letter A, Fig. 2, represents the external ease of my grater, which is cylindrical in form.

D represents the grater, which isinclosed ia case A, and is suspended on shaft e, that passes horizontallyv through the center of A.

The space between the external surface ot D l and the internal surface of the periphery of pose ot' admitting the. grated nutmegiuto the l interior of the grater D.

G represents a small brush,which is inserted in length and let into A, Fig. 1.

as represented in l F designates a spiral wire spring confined in cylinder B, and fastened at top to the circa lar wooden follower n, and resting at bottom on a similar block, (marked on.) The cylinder B, which is left open at top for the insertion of spring F, is afterward closed by the cap H.

Cylinder B has on its surface the knob t, which is designed to enter a slot near the lower edge of cap H, this slot being inthe shape of an inverted When the knob enters the lateral part ot' the slot, the cap H is held in firm position.

E represents a thumb screw inserted into the top of cap H and pressing with its lower end on the follower n.

In operating my machine the nutmeg will be placed immediately under the block m, so as to come in contact with the grating on D. The graterD is then putin motion by means of crank I, attached to shaft e. The pressure on the nutmeg is kept uniform by means of thumb-screw E. As the nutmeg is grated, it will he received into grater l) through the openings e, and can be discharged through the same openings by removing the side of cylinder A opposite to the crank.

Having thus described my machine, whatI .L cla-im, and desire to secure hy Letters Patent,
